DUST-PROOF LlD FOR CAR JOURNAL-BOXES.

SPECIFICATION forming part of Letters Patent No. 763,132, dated June 21,1904.

Application filed September 9, 1903. Serial No. 172,437. (No model.)

To all whom it may concern.-

Be it known that I. WILLIAM P. WVnsoo'rr,

r., a citizen of the United States, residing at Jersey City, county ofHudson, State of New Jersey, have invented certain new and usefulImprovements in Dust-Proof Lids for Car- Axle Journal-Boxes, of whichthe following is a specification, reference being had therein to theaccompanying drawings, in WlllCl1- Figure 1 is a longitudinal verticalsectional view of a journal-box with the lid in position; Fig. 2, afront elevation thereof; Fig. 3, a detail front elevation of the liddetached; Fig. 4, a side elevation of the lid.

The main object of this invention is to dispense with the hinge by whichthe journalbox lid is usually secured to the journal-box at its upperedge and to substitute therefor a dust-proof connection simple and cheapin construction and by which the lid may be quickly and securelyattached to the journalbox.

A further object of the invention is to so construct the dust-proofconnection that there will be no projecting ledges or lugs at the upperedge of the lid on which dirt might accumulate.

Referring to the various parts by numerals, 1 designates thejournal-box, which for the main part is of the usual construction and isprovided with the usual opening 2, which is In the under side of the topwall of this journal-box, near the front edge thereof, is formed achannel or groove 3, which extends across the box between the two sidewalls 4 thereof. The upper edge of the lid 5 is formed with aninwardly-extending tongue 6, which is adapted to fit snugly between theside walls of the journal-box at the upper edge thereof and to bearagainst the under side of the top wall. On the rear edge of this tongueis formed an upward-extending flange 7 which is adapted to enter thechannel 3 and fit snugly therein. The outer face of the tongue 6 isflush with the outer face of the top wall of the journal-box when theflange 7 is within the groove 3, so that no projecting edges are formedat the upper edge of the lid. The lid is formed with the main portion 8,which is inclined outward and downward and isadapted to rest upon thefront wall or edge of the journal-box surrounding the opening 2, andwith the upper smaller portion 9, which is vertical and is adapted torest against the vertical part of the front wall or edge of the box, thetongue 6 extending inward from the upper edge of this upper verticalpart of the lid.

Depending from the top wall of the journalbox are lugs 10, which serveto retain the upper bearing block or brass in place and Whose outersurfaces are curved downward and inward and form guides which assist inguiding the flange up into the groove 3. The lid is formed near itslower edge with an opening 11, through which is passed a bolt 12, theinner end of said bolt being screwed into a correspondingly-threadedopening in the journal-box, said bolt serving to clamp the lid in place.

Formed on the back or inner face of the lid just above the opening 11 isa lug 13, which is adapted to bear at its lower edge against theadjacent wall of the opening 2 and to prevent the lid sliding down whenthe bolt 12 is removed. In the center of the lid is formed an oil-hole14, which is closed by a sliding cover 15 and through which oil may beintroduced into the box without removing the lid.

It will thus be seen that I provide a journalbox lid of exceedinglysimple construction and Which when in position will effectually excludedust from the interior of the journalboX. There are no projecting ledgesor lugs at the upper edge of the lid to form a restingplace for dirt orgrit, and the upward-extending flange fitting in the groove in the underside of the top wall of the journal-box will effectually prevent dustand dirt passing into the box and at that point.

Having thus described my invention, what I claim as new, and desire tosecure by-Letters Patent, is

1. The combination of a journal-box provided with a groove in the underside of its top wall near the front edge thereof, a lid therefor adaptedto rest at its sides and lower edges on the edges of the opening intothe box and provided with an inward-extending tongue at its upper endnarrower than the main part of the lid and adapted to fit closelybetween the side walls of the journal-box at the upper edge thereof andagainst the under side face of the top wall of the box, the outer faceof the tongue and the outer edge of the top wall being flush, anupward-extending flange formed on the inner end of said tongue andadapted to fit within said groove, an inward-extending lug formed onsaid lid near the lower edge thereof and adapted to engage the lowerwall of the journal-box to hold the flange within the groove and a screwdevice for clamping the lid to the journal-box.

2. The combination of a journal-box provided with a groove in the underside of its top wall near the front edge thereof, a depending lug formedon said top wall the outer edge of said lug being flush with the innerwall of the groove whereby said lug will form a guide, a lid for saidbox formed with a vertical portion at its upper edge and an outward anddownward inclined part, the side edges of the vertical part and of thedownward and outward inclined part being adapted to rest on the sidewalls of the box, an inward-extending tongue formed at the top of thevertical part and adapted to fit closely between the side walls of thejournal-box at the top thereof and against the under side of the topwall of the box, the outer face of said tongue and the vertical part ofthe lid and the outer face of the top wall of the box being flush, anupward-extending flange formed on the inner edge of said tongue andadapted to fit within the groove in the top wall of the box, aninward-extending lug formed on said lid near its lower end and adaptedto rest against the bottom wall of the box, and ascrew in the lid andadapted to engage a correspondinglythreaded opening in the bottom wallof the box to clamp the lid in the box,substantially as described.

In testimony whereof I hereunto ah'ix my signature, in the presence oftwo witnesses, this 8th day of September, 1903.
